ABON Low Speed Sizers

ABON Low Speed Sizers Features of the ABON Low Speed Sizers: • ROM feed size up to 2,000 mm • Capabilities in excess of 10,000 mtph • Minimal fines creation • Insensitive to clay and sticky materials • Pre-scalping of undersize not required • Exceptionally low headroom requirements • Simple infrastructure requirements due to minimal dynamic loads placed on the supports and structure • Long wear life of consumable components due to positive bite and minimal feed slip FLSmidth ABON designs and manufactures Feeding, Sizing, Crushing and Screening equipment for an ever expanding range of industries...

ABON Sizing Principle Low Speed Sizing is one of the more unique crushing technologies in the world today. A combination of high torque and low roll speeds with a unique tooth profile in the ABON equipment leads to a specified product with a minimum of fines creation. In essence the interaction of tooth, spacer and roll set up a "Sized Void" which in turn "Sizes" oversize material when feed through the machines rolls. Undersize material basically "free falls" through the unit with little or no further size reduction. The actual rotating tip speed of the tooth or sizing element in an ABON Sizer...

ABON Sizers are suitably protected against high levels of intrusion. (i.e. flight bars, bolts etc.) and will not suffer catastrophic damage due to: • Inherent low roll speeds • Heavy duty teeth and roll construction • Underspeed sensors • Fluid coupling / trip switches These protection features are proven on commissioned Sizers operating in high intrusion colliery and mine applications. Operational Features Duty Availability ABON Sizers have been developed from Colliery and Power Station duty requirements where duty availability must be maximised. ABON Sizers are constructed with the highest...

Main Frame Fabricated from AS 1204 GR 250 carbon steel. End frames are machined from solid plate. Side frame members are fully welded, ribbed construction and machined finish to size. Side members are spigotted and bolted to end plates forming a very robust assembly capable of containing any dynamic forces created by the sizer while in operation. Shaft Assemblies The shafts and drive gears are fully machined from a solid one piece forging of AS GR4340 high carbon steel. The shafts are slotted to accept sizing segments. Shaft bearings are spherical roller C3 fit up. Oil seals are duo cone in chamber,...

Construction Features Lubrication All bearings and gears in the ABON Sizer are lubricated via “oil bath”. Each bearing and gear is lubricated via their own oil bath reservoir. Each reservoir is fitted with oil level sight glass, magnetic drain plug and oil sampling point, (to assist with condition monitoring). These areas are easily accessible for maintenance and monitoring. Sizing Teeth ABON Sizing teeth are designed to slide into machined slots in the shaft, without the need to remove the shafts form the main frame. Teeth are held firmly in the shaft by clamp plates. Each row is individually...

Wheel Assemblies Abon sizers are fitted with fully retractable hydraulically operated wheel assemblies. These wheel assemblies allow units to easily be removed for servicing. When units are in operating position with wheels retracted, they can be set on rubber sealing strips and require little or minimal anchoring. Surface Protection The machine is sandblasted to a class 2.5 finish and then two pack epoxy under coat, followed by a two pack polysiloxane top coat. All rotating and stationary duo cone seal housings are protected by a baked molybond coating to the exposed surfaces. Protective Devices...
